BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle loading apparatus used for a passenger car, a transport vehicle, and the like, and more particularly to a vehicle loading apparatus for recognizing an identification tag attached to an article or the like.

As an ID technique for identifying an article or the like, a bar code, an optical character reader (OCR), and the like are widely used in the past. The bar code has the advantage that the unit price of the tag attached to the surface is low, but the bar code reading device is expensive and the amount of information is limited. In addition, while OCR is used as an easy optical reading device, it is difficult to improve reading accuracy. Therefore, in recent years, RFID (Radio Frequency Identification) which attaches a tag to a person or a thing and identifies individual information by a radio wave through the antenna which relays communication has attracted attention.                         

For example, in RFID without a built-in battery, a tag first composed of an ID memory and a communication circuit, for example, a CM0S chip and a small loop antenna, is attached to an article. Toward this tag, radio waves (charge waves) are emitted from the reading device (reader), and the energy necessary for the response operation is supplied to the tag. The tag supplied with this energy obtains electric power by the principle of electromagnetic induction and transmits ID data, for example. The reader changes to the reception state after the radio wave transmission to the tag, and can recognize the ID of the tag by reading the ID data. Examples of RFID transmission methods include an electrostatic coupling method, an electromagnetic coupling method, an electromagnetic induction method, a microwave method, and the like. In the transmission system using the microwave system using the microwave wave propagation, it has begun to appear that the maximum communication distance reaches up to 5 m to 10 m.

Even in the retail industry, the use of RFID for product management is rapidly spreading. For example, it is already a feasible technique to attach RFID to various articles and to read product information such as a manufacturing country, a manufacturer, a product name, a serial number, and the like. In the near future, it is well anticipated that the era of RFID will be granted to all goods in the world. As a technique using RFID, there is conventionally a technique of acquiring a passenger's ride status from an identification tag such as RFID and confirming the passenger's riding down (for example, Patent Document 1 (Japanese Patent Laid-Open No. 2003-30707). (Fig. 3-4, Figure 1)).

On the other hand, various items may be placed in the interior of a car. In ordinary passenger cars, it is possible to store precision parts such as cigarettes, lighters, cameras and personal computers, media such as CDs and MDs, foodstuffs such as alcoholic beverages, carbonated drinks, and the like. For example, if a dangerous object such as a lighter is left inside a car, it may cause an unexpected accident such as ignition. In addition, when a user forgets that the precision parts, foodstuffs, etc. are left inside the car and parks the car in hot sunlight, it causes failure, corrosion, or rupture of these items. For example, in countries / regions with special legislation such as the United States, it may be prohibited by law to place alcohol in the interior of the car.

In addition, in a delivery vehicle such as a courier service or a general transport vehicle, there is a possibility that all articles are placed in a vehicle (indoor car or in a luggage compartment). With regard to the delivery items placed in the interior of the car or the interior of the luggage compartment, it has conventionally taken a considerable amount of time to confirm their existence, and most of the labor time required for delivery has been spent on the confirmation of the delivery parts. In Patent Document 1 described above, it is only possible to confirm the ride of the rider, and no mention is made of the handling of articles accompanying the position information of the car, the state of the car, and the like.

SUMMARY OF THE INVENTION The present invention has been made to solve the above technical problem, and an object thereof is to provide a vehicle loading device that enables a user to easily grasp an article present in a vehicle.

More specifically, the controller determines whether the article having the identification signal becomes a dangerous article when placed in a vehicle, and outputs information prompting the user to the user when the article can be a dangerous article.

Here, further comprising a position information measuring system unit for recognizing the position of the vehicle, the control unit is configured to determine the effect when the article is placed in the vehicle based on the position recognized by the position information measuring system unit, For example, it is preferable at the point which can provide a user with information according to the law regulation in a specific area.

On the other hand, the on-vehicle device according to another aspect of the present invention reads, by the identification signal reading means, the identification signal of the identification tag attached to the article present in the vehicle, thereby reading the information of the article corresponding to the read identification signal. Acquisition means acquires from the storage means by the acquisition means, and position information about the current position of the vehicle by the position information acquisition means. And the information of the article acquired by the article information acquisition means is reflected in the position information acquired by this position information acquisition means, and it outputs by the output means. Here, the map data based on the positional information acquired by the positional information acquiring means is acquired from the map data acquiring means, and the information of the article acquired by the article information acquiring means is reflected in the map data acquired by the map data acquiring means. It can be configured to output from the output means.                     

The on-vehicle device according to another aspect of the present invention acquires, by the article information acquiring means, information of the article corresponding to the identification signal based on the identification signal that can be read from the identification tag of the article present in the vehicle, Map data used for indicating the travel position of the vehicle is acquired by the map data acquisition means. And the information of the article acquired by the article information acquisition means is reflected on the map data acquired by this map data acquisition means, and displayed by the display means.

Next, the operation of the on-vehicle device 1 described with reference to FIGS. 1 and 2 will be described using a flowchart as necessary.

In communication, the RFID reader 50 first transmits radio waves from the radio frequency module 52 to the RFID tag 70 through the antenna 51 under the instruction of the control module 53, and then transmits the radio waves to the RFID tag 70. Supply energy for response. Thereafter, the RFID reading unit 50 switches from the transmitting state to the receivable state, and the RFID signal is received by the radio frequency module 52 through the antenna 51. The radio frequency module 52 converts the received signal into a digital signal and performs an error check or the like. The obtained RFID is transmitted to the system controller 10 via the interface 81.

3 is a flowchart showing processing executed in the control unit 11 of the system controller 10. The control unit 11 reads the identification signal (RFID) of the article obtained from the RFID tag from the RFID reading unit 50 (step 101). That is, the RFID reader 50 receives the identification signal RFID of the article from the RFID tag 70 which is the identification tag attached to the article placed in the vehicle interior or the luggage compartment as described above. ) Reads this RFID via the RFID receive I / F 15. Thereafter, the control unit 11 checks the read RFID against the RFID database 61 to obtain information (product name, manufacturer, serial number, type, etc.) of the article (step 102).

On the basis of this acquired information, the control unit 11 determines whether or not the article on which the RFID is read is a "dangerous article" which is dangerous when placed in a car interior or the like (step 103). In the case of dangerous goods, the user is warned (step 104), and the process proceeds to step 105. If no dangerous goods are present, the flow proceeds to step 105 as is. As the warning processing, for example, a method of displaying the contents such as "Hazardous materials are left inside the car" on the display device 41, or using the audio device 42, for example, may indicate the name of the dangerous goods. How to read.

In step 105, a list of articles placed in the car interior or the luggage compartment interior before the end of the processing is displayed.

4 is a diagram illustrating an example of a list displayed on the display device 41. Here, a list of article names in which RFID is recognized is divided into a vehicle interior and a luggage compartment interior. In this example, an alarm display for the dangerous goods found is performed along with a full list display of the article. At this time, only the article designated by the user may be extracted and displayed. In step 105 shown in FIG. 3, after such display is performed, a series of processings shown in FIG. 3 ends.                     

Next, the method of providing (outputting) the article information based on the detected positional information of the vehicle will be described.

The vehicle is private property, and it is inherently personal freedom to take any goods inside the car. However, if there are countries or regions that are legally regulated in articles to be carried in the interior of the car, there may be certain restrictions even if they are said to belong to individuals. For example, in the United States and Canada it is forbidden to bring alcohol into the interior of a car. Therefore, in this embodiment, it is comprised so that appropriate information about an article may be provided according to the position, the situation, etc. which a vehicle exists.

5 is a flowchart showing processing executed by the control unit 11 of the system controller 10 for various restrictions and the like. First, the control part 11 reads RFID of the RFID tag 70 acquired by the RFID reading part 50 (step 201). Next, the control unit 11 determines the current position of the vehicle from the GPS receiver 21 of the position information measuring system unit 20 (step 202). Further, regulatory information is obtained from the regulatory information database 62 of the database 60 (step 203). Then, from the acquired current position and acquired regulatory information, it is judged whether or not a vehicle exists at the regulated position, for example, a country, a specific state such as the United States or Canada, etc. (step 204). If it is not a regulated position, the control unit 11 checks the read RFID against the normal RFID database 61, and acquires information (product name, manufacturer, serial number, type, etc.) of the article (step 205). The process proceeds to step 207. On the other hand, if it is determined in step 204 that it is a regulated position, the information (product name, manufacturer, serial number, type, etc.) of the article is acquired (step 206), in contrast to the RFID database 61 for regulated positions. Then, based on the information of the acquired article, it is determined whether it is a dangerous article or a regulated article (step 207). For example, if you are located in the United States or Canada, if alcohol is in your car, then you are in control. If it is not a dangerous goods or a restricted goods, the display based on the information of the acquired goods is performed with respect to the display apparatus 41 (step 209), and a process is complete | finished. If the dangerous goods or the restricted goods exist, a warning process is performed by the audio device 42 or the display device 41 (step 208), and the process proceeds to step 209 to end the process.

As described above, in the present embodiment, the influence when the article having the obtained identification signal is placed on the vehicle is determined, and the determination result is output. For example, the presence of items that require attention when placed inside a car and items that should not be carried with care can warn or warn the driver to prevent accidental accidents or penalties for violation of the law. . At this time, based on the location information from the GPS receiver 21 and the like of the location information measurement system unit 20, the driver can be provided with more appropriate information to the user by providing a warning according to the country and region where the vehicle exists. Can be.

Next, the application example to the logistics system to a present Example is demonstrated.

Mail and collectibles, such as a courier service, generally have the tag which described the destination. Here, if the RFID tag in which the destination information is stored is attached as this tag, the person in charge of collection can grasp the situation of the luggage compartment in real time by acquiring the RFID. In addition, if the current position is determined by the position information measuring system unit 20 and the position information of the destination obtained from the collection information database 63 is obtained, the optimal collection course without waste is selected and the information is sent to the person in charge of the collection. Can provide. In addition, by reflecting the congestion information obtained from the VICS receiver 22 or the like, it is also possible to provide a delivery person in charge with a collection course that can be collected in a shorter time.

6 is a flowchart illustrating an operation during collection. The RFID reader 50 reads the RFID including the destination information from the RFID tag 70 attached to the article inside the luggage compartment, for example, by the antenna 51 (see FIG. 2) installed in the luggage compartment (step 301, the read RFID is outputted to the control unit 11 of the system controller 10. At this time, the destination information included in the read RFID is displayed on the display device 41 (step 302). FIG. 7A shows an example of a list displayed on the display device 41, and the situation inside the luggage compartment is illustrated. In the example shown in FIG. 7A, four articles A to D placed in the luggage compartment are displayed, and the address of the destination is displayed for each. It is also conceivable that the form in which the destination information is not included in the RFID. In this form, the destination information corresponding to the acquired RFID is stored in the collection information database 63, for example. In this case, the situation display in the luggage compartment may be performed on the basis of the destination information read out from the collection information database 63.

Here, the control unit 11 determines the current position of the vehicle from the GPS receiver 21 of the position information measuring system unit 20 (step 303). Further, collection information is obtained from the collection information database 63 of the database 60 (step 304). The control unit 11 calculates the position information of the destination in the article from which the RFID is read from the obtained collection information (step 305). In addition, the display device 41 displays the positional information of the destination stored in the RFID (step 306).

Then, congestion information is obtained from the VICS receiver 22 of the position information measuring system unit 20 (step 307). Further, based on the obtained congestion information, the shortest collection path is calculated for the positional information of the destination displayed on the display device 41 (step 308). Thereafter, the calculated shortest collection path is displayed on the display device 41 (step 309), the route guidance is started (step 310), and the processing ends. FIG. 7B illustrates a case where the guidance display of the shortest collection path is made. In the example shown in FIG. 7B, articles A to D identified by the RFID are read by the map data reading system unit 30 based on the position measured from the position information measuring system unit 20. Posted on the map. At this time, it is assumed that the VICS receiver 22 recognizes that there is a congestion portion from the current position to the delivery position of the article D. In this case, based on the positional information of the article from which the RFID is read by the system controller 10, the rescan of the collection path avoiding the congestion portion is performed. The result is output from the system controller 10 to the display device 41, and the congestion avoidance path as indicated by the broken-line arrow in Fig. 7B is displayed on the screen of the display device 41. In this way, by applying the RFID recognition to the collection work using the vehicle navigation system, the collection can be performed in a shorter time.

As described above, according to the present invention, the user can easily grasp the article existing in the vehicle. In addition, it becomes possible to provide the user with the information of the article according to the position or the situation in which the vehicle exists.
